[0002] With the development and unification of computer technology and network technology, it has become the trend of modern multimedia development. The so-called multimedia refers to the comprehensive expression of information formed by the fusion of various media, including the fusion of text, sound and images. Therefore, the use of computer Cooperate with a projector to form a relatively mature multimedia audio-visual equipment. When installing multimedia audio-visual equipment, auxiliary devices can be used to assist the installation of audio-visual devices. Projection angle, specifically speaking, it is convenient to adjust the projection angle of the projector. At present, the existing multimedia audio-visual installation auxiliary devices are usually brackets with relatively simple structures. Although their cost is relatively low, they cannot be quickly and automatically Adjusting the placement angle of multimedia audio-visual equipment cannot adapt to the development of the market
